5 - Connections Connecting other equipment This is an example of US-4x4 connections. 88 Precautions before making connections oo Carefully read the operation manuals of the devices to be connected and then connect them correctly. oo Before making connections, turn this unit and all equipment to be connected off (standby). oo If possible, install all connected devices so that they are powered from the same AC power supply line. When using a power strip or similar device, be sure to use one that has high current capacity in order to minimize voltage fluctuations in the AC power supply.

When the USB connection is working, the USB indicator on the front of the unit lights. CAUTION If you connect this unit to a computer via a USB hub, for example, audio signal dropouts, clicking noises and other interference could occur due to the influence of other USB devices connected to that hub. For this reason, we strongly recommend connecting this unit to a separate USB port. Connecting USB keyboards and mice, however, to the same bus should not be a problem. Audio connections Analog audio signals input into this device from mics, guitars, keyboards and other audio equipment can be converted into digital signals and transmitted to the computer via USB. In addition, by connecting speakers (through an amplifier if not powered) or headphones to this unit, you can monitor audio signals that are input to this unit and output from the computer. CAUTION Before connecting audio equipment, set the GAIN, LINE OUT and PHONES knobs to their lowest values. Failure to do so could cause sudden loud noises from monitoring equipment, and this could damage the equipment or harm hearing. Microphones oo Dynamic mics Connect these to the IN1/IN2 jacks (and US-4x4 IN3/IN4 jacks) on the front of the unit oo Condenser mics When using condenser mics that require phantom power, connect them to the IN1/IN2 jacks (and US-4x4 IN3/IN4 jacks) on the front of the unit, and set the phantom power switch to +48V. When the phantom power switch is set to +48V, the phantom power indicator on the front of the unit lights. CAUTION • Before making connections, turn this unit and all equipment to be connected off (standby). • The phantom power switch changes the setting for both US-2x2 input channels (all four US-4x4 input channels) simultaneously. Do not turn phantom power +48V when connecting a mic that does not require phantom power. • Do not connect or disconnect mics while phantom power is +48V. Doing so could cause a loud noise and might damage this unit and connected equipment. • Set the LINE OUT and PHONES knobs to their minimum values before turning phantom power +48V/OFF. Depending on the connected mics, sudden loud noises from monitoring equipment could occur, and this could damage the equipment or harm hearing. • Set the phantom power switch to +48V only when using a condenser microphone that requires phantom power. Turning phantom power +48V when a dynamic mic or other mic that does not require it is connected could damage this unit and connected equipment. • When using condenser mics that require phantom power and dynamic mics together, be sure to use balanced dynamic mics. Unbalanced dynamic mics cannot be used when phantom power is enabled. • Supplying phantom power to some ribbon mics will break them. If you are unsure, do not supply phantom power to a ribbon mic. Guitar When connecting a guitar or bass guitar directly to this unit, use the IN1 or IN2 jack on the front of the unit and set the MIC/LINE INST switch for that jack to INST. TASCAM US-2x2/US-4x4 11
